Typical CdSe size series, as obtained through hot-injection based synthesis. Samples are placed under UV excitation to show the concept of quantum confinement: smallest nanocrystals emit in the blue, where the larger crystals emit in the red to near-infrared.

Welcome

Welcome to the website of the research group ‘Physics and Chemistry of Nanostructures’ (PCN) at the department of Inorganic and Physical Chemistry of Ghent University. The site provides you with information on our research projects, equipment, publications, ... in the field of nanoscience and nanotechnology.

Our research focuses on colloidal nanocrystals, an ideal starting point for multidisciplinary science where chemical synthesis and processing techniques are combined with the characterization and application of physical properties. Our group welcomes collaborations in this field, offering knowhow in synthesis and characterization of a number of semiconductor and metal colloidal nanocrystals.

In the beginning of January a new Transient Absorption (TA) setup will come to our lab. The TA spectrometer will be coupled to the exisiting ultrafast laser (and amplifier) system to enable pump-probe spectroscopy with femtosecond time resolution...

We report on a time-resolved study of the photoluminescence of core/shell CdSe/CdS dot-in-rod colloidal nanocrystals having various geometries. By studying the exciton recombination dynamics, we unveil a quadratic dependence of the bright–dark...

We report on the synthesis of luminescent CdSe/CdS@SiO2 nanoparticles and their application to cell labeling. The main novelty of these nanoparticles is the use of newly developed "flash" CdSe/CdS quantum dots (QDs), which are obtained through a new...
